EDIT: It works, but now it is adding someone without the live and that's not me. I don't even think that's a profile that exists.

Just leave your Skype button on your signature like what you just did and don't bother to put it on the MPGH option area.
Live:boomer00oo and boomer00oo are two different Skypes. This is the different like what Ameer said about using outlook as your Skype.
If you do not include the Live, then that is not your account.
